RUT955 blocking access to remote server
Hi, I use the RUT955 at our offices as our main internet gateway manager, as we have a main WAN connection through the WAN ethernet port, and have the Mobile connection acting as a failover, as we have regular internet connectivity issues.
We also have a cloud hosted server (with a static public IP) that we use for data processing that connects via VPN.
RUT955 Firmware: RUT9XX_R_00.06.09.2
We always were able to connect to the cloud server via RDP, but all of a sudden the server cannot be pinged, connected to via RDP and as a consequence the VPN is not running.
The strange thing is that when running a trace route to the cloud server it keeps getting stuck on the RUT955's IP. (I'll attach a screenshot)
As a test I temporarily disabled my PC's firewall and antivirus, but nothing seems to change. I also set up a traffic rule the specifically allows both incoming and outgoing traffic to that IP, but still have had no joy.
The strangest thing is that if I set up my mobile as a hotspot and connect to it, there are no problems, but as soon as the RUT955 is handling network traffic everything falls apart.
I have upgraded to the latest firmware, reset the RUT955, downgraded it to an older firmware, checked the cloud server's firewall and networking rules, but so far I have had no success.
The strange thing is no configurations have changed on the RUT955 or the cloud server.
I don't know if I'm missing something really simple, but I'm currently at a loss on how to proceed further. Any help would be highly appreciated
